12th or 13th century chivalrous poetry from South of France was still full of feelings and what have you, and a little earlier the Arthur-related stories were not void of feelings either. I personally blame the “Protestant ethic”, for lack of a better name, which started culturally imposing itself starting with the mid-1600s in England and present-day Netherlands (in the early 1600s a guy like Shakespeare was still not afraid to share his feelings in his Sonnets).
